Any VB2008 code that would allow me to download files through my program (like an update service), without it freezing, while displaying the progress like that of IE7, etc... using a progress bar, and that displays the size and speed?
View 4 Replieshow to implement such a thing , i am currently programming a compact framework vb.net this is what i have done and am stuck,what ive learn is very basic and simple i am using a sqlce query to use it to search for any string matching entries in the database and then it will display it something like google search engine.And am using visual studio 2005, what ive done is that i will use the datareader to search for the rows in the database and then i will have to assign them to something that is similar to google search engine a dropdown list of similiar results but am not sure how. What im doing is for the user to search for a particular salesman name and then have a progressive search function to also help the user to complete typing rather than typing the full words

I'm trying to create a shaped form with an attractive shadow effect by painting progressive alpha blended layers underneath the main visible form area (a background mask color has also been set to allow a shaped form). This is going well, but I have one major problem to resolve - the bottom shadow layer does not appear as the correct transparent shade - it always appears solidly as the background color / transparent mask color for the form.
Why does this bottom shadow layer not show up as transparent, and why is this color being shown when it is set as the transparency key for the form (and so should be invisible anyway)???[URL]..
I want to download xsd specifications from a web service and automatic converting (serialize) these schemas to classes (visual studio - vb.net). If the organization that is responsible for the xsd schemas alter them in a way that only my class corresponding to the xsd have to be altered (not the rest of my code) I would like to automatic update my xsd corresponding class.
I use vs2010. What I want to do is: call a web service where I can send in an input parameter to the service which specifies the xsd I want to retrieve (the service is GetShemaDefenition and returns an object with the schema specification in a string property of the object). I den have to read the xsd string from the string property and convert this to a class representation of this xsd specification. Is it possible to do this automatically? I have done this manually by using xsd.exe. If the owner organization of the xsd has altered the xsd specification, I have to test if there is a new specification, and if there is I have to build a new class representation of this xsd? Is it possible to do what I want? And how would I know if it has been a big change in the xsd which also affect other parts of my code, not just the class representation of the xsd?
Update:I use one web service where one of the properties is a string. The string is an XML inside a CDATA block. The organization which provides the web service will not pares the xml inside the CDATA block but instead forward this to another organization that will use the xml data. The organization which uses the xml data specifies the xsd schem that I have to follow to generate my xml correct. This is the xsd schema I can get from another web service. I don't really understand what I can do with this xsd file from the web service. What can I do with it and why do I want to download it from the web service, when I can't use it automatically? Because I have to manually do the changes when the xsd changes I can easily download the xsd schema from the organization's home page and make the new class with xsd.exe.

View 4 Repliesi have made a program and added a update check button.If an update is available it lets the user know and if they click update a hidden webbrowser goes to the download address like:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WebBrowser1.Navigate("http://mydomain.com/myprogram.exe") End Sub Well this works and prompts the user with a file download dialog(default for windows)

I am writing a vb.net client application that uses a web service to connect to the remote database.So far I am able to connect to the web service and read, add new and delete data from the database. I am having a hard time updating data.
I have a datagridview control that is bound to a dataset retrieved from the remote database using the web service.When a record is edited in the datagridview control, I need the dataset that is bound to that control to be updated and then that updated dataset to be sent to the webservice to update the remote database.
My client code in the btnUpdate_Click event
dim new_ds as new dataset = datagridview1.datasource
Dim es As New testwebservice.equipmenttracker 'the web service reference
dim msg as string = es.updateequipment(new_ds)
messagebox.show(msg)

I am trying to figure out an easy way to add custom plugins for the app for additional features, without people having to download a whole new update each time.i guess the way i'd want it to work is,the program will auto detect the plugin file. Then, add's a specific value to either a button array, or add's a picture, etc.Once that button is clicked, it will open a new form designed the way i want it. from within the plugin itself.So its a module.What would be the easiest way to do this?

I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.
Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

View 4 RepliesThis is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
